BOLT-F RAME FOR SAFES OR VAULTS.

SPECIFICATION forming part of Letters Patent No. 789,217, dated May 9,1905.

Application filed December 5, 1900. Serial No. 38,777.

To all whOm it natty concern.-

Be it known that I, WILLIAM H. HOLLAR,

of Philadelphia, in the State of Pennsylvania, have invented certain newand useful ImprovementsinBolt-FramesforSafesorVaults, whereof thefollowing is a specification, reference being had to the accompanyingdrawings.

My present improvements relate to that portion of a safe or vaultstructure in which the slide-bolts of the locking mechanism are directlymounted for reciprocation. As ordinarily constructed, the framework forthe purpose specified is composed of a plurality of separate andindependent bars assembled upon and separately attached to the innerface of the safe or vault door and only united by the body of said door.Consequently when said ordinary construction is employed the preciseadjustment of the boltwork must necessarily be deferred until the dooris erected and the aforesaid separate bars of the boltframe areassembled thereon.

My invention provides a bolt-frame Which is a unitary structure distinctfrom the door and comprising inner and outer walls connected in integralrelation, said frame being provided with alined bolt-bearings in saidwalls and means to secure said frame to the door, as hereinafterdescribed.

My invention comprehends the various novel features of constructionand'arrangement hereinafter more definitely specified and claimed.

In the accompanying drawings, Figure 1 is an inner face view of acircular door to which is applied a unitary bolt-frame convenientlyembodying my invention. Fig. 2 is a top plan view of the structure shownin Fig. 1. Fig. 3 shows in outline my preferred form of undercut rib andslideway.

Referring to Figs. 1 and 2, A is the circular body of the door Whoseinner face A is provided With a plurality of parallel channels orslideways A comprising oppositely-undercut parallel edges (0 The unitaryboltframe B is provided with a plurality of parallel ribs B, comprisingoppositely-undercut parallel edges 6, accurately ground or otherwisefitted to slide in said channels A as indicated in Fig. 3. The annularWalls B B of said frame bridge the door from channel to channel andconnect the frame-ribs in rigid relation, thus insuring absolutealinement and registry of the ribs in their respective channels. Saidframe-walls B B are respectively provided With bearings b b for theslide-bolts C of the locking mechanism, and the rigid maintenance ofsaid bearings in proper registry is absolutely determined by the unitaryrelation of the portions of the frame comprising them.

It is to be understood that in the operation of my invention the door ismanufactured with channels arranged to receive'the boltframe, and whenerected said frame is slid into its predetermined position and secured,the absolute registry of all of the slide-bolts being thus assuredwithout the laborious assembling and fitting of parts at the place oferection required by the ordinary methods of construction beforedescribed.

It is to be understood that the interlocked undercut edges of the doorchannels and frame-ribs effect such a union between the door and frameas to prevent their. separation by any force applicable to the door Whenin position; yet the arrangement described permits the frame to bereadily removed from the door for repairs, &c., by relative movement inthe direction of the length of said channels and ribs, accidentaldisplacement of the frame upon the door in said direction being normallyprevented by the bolts D or other convenient fastening devices.

I do not desire to broadly claim the use of undercut channels and ribsin safe or vault construction, but do not desire to limit myself to theprecise construction and arrangement described, as it is obvious thatvarious modifications may be made therein without departing from theessential features of my invention.

I claim- 1. A unitary bolt-frame for a safe or vault, comprising abridge portion composed of in ner and outer walls, connected in integralrelation by a plurality of Webs; and, alined bolthearings in said Walls,substantially as set forth.

2. A unitary bolt-frame for a safe or vault, comprising a plurality ofparallel ribs pro,- vided with oppositely-undercut parallel edges; and abridge portion of said frame composed of inner and outer walls connectedin integral relation by a plurality of Webs; and, alined boltilbearingsin said walls, substantially as set fort 3. A unitary bolt-frame for asafe or vault, comprising a bridge portion composed of inner and outerannular walls; a plurality of webs connecting said walls in integralrela tion; and radially-aimed bolt-bearings-insaid walls, substantiallyas set forth.

4. A unitary bolt-frame for a safe or vault, comprising. a bridgeportion composed of inner and outer annular walls; a plurality of Websconnecting said Walls in integral relation; radially -alined bolt-bea-rings in said Walls; and, a plurality of parallel ribs providedwith oppositely-undercut parallel edges sitely-undercut parallel. edges,parallel with a diameter of thedoor; of a: unitary bolt-frame comprisinga plurality of parallel ribs pro- 1 vided withoppositely-undercutparallel edges fitted to the slideways in said door; a bridge portion ofsaid frame composed of inner and outer annular walls integgl-ailrelation with I saidriibs; webs transversely connecting said walls inintegral relation; and radlally-ahned bolt-bearings said. walla, substantial-Lv as: set

forth.
